Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a directionally adjustable low voltage luminaire with a spotlight reflective cap that provides a full cone of light.

[Conventional technology]

Low voltage lighting fixtures with cold source reflection, 12V, 50W halogen lamps are known. This type of halogen lamp emits bright light and does not produce heat due to the emission of light.

However, a disadvantage of this type of lighting is that complex holders are required in order to adequately illuminate any part of the display wall or display board where it is needed.

[Problems to be solved by the present invention]

The object of the invention is to provide any L display board installed in the form of a display board or a Spanish partition wall and held by connecting members.
It must be able to be fixed to a point D or to a pipe, and to be easily adjustable in height and direction.This makes it possible to adjust the distance of the full cone from the point to be illuminated, and also to adjust the light cone to any angle of inclination. The object of the present invention is to provide a directionally adjustable low-voltage illumination device that can be directed at a location to be illuminated.

[Problem 1ft: Means for Solving] The gist of the present invention that solves the above problem is as described in claim 1. Advantageous configurations are described in claims 2-9.

[Actions and effects of the present invention]

According to the groove bottom of the present invention, a lighting fixture can be quickly and easily fixed to an arbitrary plate or pipe that holds a pipe. In that case, the full cone 7 can be simply adjusted at a desired distance and in a desired direction from the opening to be illuminated, thereby allowing it to be placed at a predetermined location on the plate. It can be illuminated as desired.

Without burning your hands or breaking the electrical connection between the luminaire and the power supply, you can grasp the hot insulation board with the knurls of the spotlight reflective cap and turn the round cone into a It is particularly effective because the angle can be adjusted up to 660°.

Furthermore, since the two rods that support the lighting fixture are supported only by friction within the holes in the holder, the rods can be expanded and contracted arbitrarily by simply moving the rods in the axial direction within the holes in the holder. This allows the lighting equipment to be brought closer to the area to be illuminated, and
The lighting fixture can be oriented in any direction.

In addition, lighting fixtures can be fixed at any point on the board serving advertising purposes or on the pipe holding this board; It is advantageous that the screw clamp can be tightened directly, and that when attaching the screw clamp to the plate it can be tightened with the same clamping jaw half, so that the same screw clamp can be used in both cases.

Furthermore, it is possible to manufacture the axial pin of the central swivel joint from a metallic material and to manufacture this axial pin economically to produce the required axial preload of the joint part, such as the rotating plate of the swivel joint. This is advantageous because it also ensures the desired electrical insulation of the electrically conductive parts, which allows for a very simple construction of the fastening element.

A screw hole is provided extending perpendicularly to C, and a set screw 16 is screwed into this screw hole, whereby the lighting fixture 1 is fixedly tightened to prevent it from falling from the holder. .

The insulating plate 8 has rotating plates 9, 9' located adjacent to each other on both sides thereof.
Friction linings are provided on both side surfaces of the insulating plate 8 and on the surfaces of the two rotary plates 9, 9' on the insulating plate side to cause rotational entrainment. The end surface of the insulating plate 8 is provided with a groove 9, so that the insulating plate 8 can be easily grasped by a person, and the rotating plates 9, 9' and the lighting device 1, which are frictionally entrained, can be easily grasped by a person. Can be rotated in any direction. This directs the cone to the desired illuminated location. In that case, when this unit rotates, the lighting fixture 1

With such a bearing of the luminaire 1 in the swivel T,
By means of the stopper of the spotlight reflection cap, the full cone produced by the illumination device and thus its spotlight reflection camp 3 can be rotated by an angle of 330" within a range of only K mJ, thereby making it possible to Approximately the desired angular adjustment is achieved.

The two rods 17 are supported by their ends facing away from the luminaire 1 in a bore 19 of the holder 20 such that they can freely rotate under friction and can be freely axially displaceable. A connecting element is preferably used as the holding body 20, in which the hole 19 is provided.
is provided and the rod 17 is held in this hole by friction. The distance between the lighting fixture and the board 21 with the 20ft connecting member attached? If you want to make it smaller, use friction to make the hole 1 of the mating member smaller.
It is only necessary to move the rod supported in 9 downwards together with the luminaire into the hole 19 of the coupling member.

Both rods 17 and 17' are arranged at a predetermined interval, and both rods can be rotated without touching each other.
By twisting and rotating the rod together with the lighting fixture 1 about the longitudinal axis 22, the lighting fixture 10 can be turned by an angle of 6400 degrees. This rotation is performed as in the case of the ulna and tibial bones in the human body.

This type of low-voltage lamp consumes only 50 watts of power, produces approximately 150 watts of illumination compared to other lamps, and generates very little heat compared to common glow lamps.

The rod 17 is generally made approximately 60 cm long, so that upon suitable orientation adjustment, arbitrary illumination of the desired area can be obtained in each case, which is especially true when the illumination devices 1 are arranged independently of each other and at right angles to each other. In short, the pivoting is achieved by the rotation of the swivel T about the axis of rotation 11 and the torsional rotation and trapping of the rods 17, 17' about the longitudinal axis 22. In that case, the turning range is a maximum angle of 340° when the rod is fully extended.
